9mm Pistols Help
The Beretta won't have an over-travel adjustment as a stock option. Having an over-travel stop is a big issue for performance. As a result, you will have to buy a steel trigger to replace the plastic one (costs about $15). Drill a hole in the trigger as high up as it can be, tap it out for 6 x 32 tpi and install a set screw so that you've got an adjustable over-travel stop.
The M9 Beretta is just one of the most well know pistols worldwide, entering United States military service in the mid 80s. As a result of its quality craftsmanship and high durability, it has the capability to fire under extreme heat and cold as well as after being buried in mud, sand, snow and salt water. Add in a high capacity magazine in addition to a low recoil, it is easy to find out why the M9 quickly became the common sidearm for military personnel.
To be accurate for bullseye pistol shooting, the barrel must be match grade. Bar-Sto and KKM Precision both make good barrels for the Beretta 92 (Going to aula.sar.edu.co), and you will get excellent results from just using a drop-in barrel. Contrary to common belief, there's absolutely no need to use a bushing at the front of the barrel to improve lock-up on a Beretta. The barrel locks up at the back against the slide using the locking block that is attached to the barrel, so it really is crucial that your locking block is tight and in good condition. In the event you are installing a barrel that will require fitting, you will be removing material from the back of the barrel until the gun will go into battery reliably. Make sure and apply Dykem or other layout fluid between removing material to determine where the contact points are. You want as much contact as is possible between the back of the barrel and also the breech face on the slide. Some barrels (Bar-Sto) have extra material together with the back of the barrel and some of this must be removed slowly. The point of the extra material on these barrels is to get a tighter lockup with more contact surface, plus center the back of the barrel vertically on the breech face.
The UHC M9 features a spring pistol firing mechanism which permits its users to shoot as fast since they can cock the gun. This is a great pistol if you're just beginning to get into Airsoft or if you just want to shoot some cans within your basement or backyard. You definitely will enjoy hours of fun while you take down your targets with a deadly aim. In contrast, if you are already an avid Airsoft enthusiast, then the UHC M9 is a must have for your collection. Within any case, this pistol delivers great performance at a very low price.
To improve lockup, some guns have set screws installed running up under the frame rails through the back of the barrel to give extra contact points while everything is locked in battery.
To improve service life, some gun builders modify the frame rails and replace sections of the aluminum rails with pieces of steel, affixed with screws. This really is only necessary in case you are a top level competitor and need that extra 2% performance that comes with a super tight frame-to-slide fit, plus the durability of steel on steel vs steel on aluminum. You'll find no "kits" for doing this sort of work, so you will have to have this type of work completed by someone that knows what they may be doing. This kind of improvement of slide-to-frame fit is similar in nature to the "Accu Rail" improvement that used to be done on 1911 style pistols.
Inevitably, sights. If you replace the rear sight by having an over-sized adjustable sight, it really is common to need to trim down the top of the firing pin blocker lifter to keep it from hitting the bottom of the sight. Additionally you will have to get a taller front sight. The front sight may be welded on (less common) or you can get one that slips over the stock front sight and pins in place (more common) or you may get the slide milled out with a dovetail (uncommon). Beretta makes an adjustable rear sight that allows you to keep the stock front sight and not have to modify the blocker lifter, but it is more low-profile than most competitive shooters are going to want.
